Hey hey,

Need some help finding a Class 1 Div 2 explosion proof (spark free) mag lock or surface RIM strike.

Anyone no where to start looking? Schlage, SDC, Allegion, RCI, all said nothing.

Still navigating through Assa Abloy......

Wow, what an interesting application. It actually makes good sense to have hazardous rated door hardware, yet it doesn't seem to exist!

I found an pneumatic door (think auto open/close like a spaceship) that is Class 1 Div 1 rated, but haven't turned up any strikes yet.

I've asked some people at Assa and Allegion for help. I'll post their replies.

I believe a mag lock or strike would be considered intrinsically safe but have seen maglocks and other devices by www.erichindustries to be certified Class 1 Div 2. E-HD176/24
